健康資訊交換平臺對新冠肺炎防疫效益評估

Evaluation of the Effectiveness of Health Information Exchange Platform on the COVID-19 Contain

目的：評估HIE平臺使用者對其效益評估，特別是平臺加入新冠肺炎(COVID-19)資訊、防疫措施等是否具效益，能增強平臺使用者繼續使用之意願。
方法：使用32題結構式HIE平臺效益評估問卷，以南部某醫學中心HIE平臺使用者為對象，調查期間2020年4-5月，有效問卷共121份，回復率為33.6%，與母群體無顯著差異。
結果：使用因素分析之方差最大正交旋轉法後，測量變項予以歸併成為五項因素其累積變異數貢獻為82.95%，于HIE平臺于五項因素得分上，僅有填答者為醫師時有統計上顯著差異。前述五項因素能有效預測使用者是否繼續使用HIE平臺，其預測力為68.64%。
結論：HIE平臺資訊與服務品質、防疫資訊內容有用性、平臺介面功能與運作、對防疫效益及資源利用有效性等因素是顯著影響繼續使用平臺的預測因數。

Objective: Widespread health information exchange (HIE) was motivated by the National Health Insurance Agency for improving coordination of care and reducing costs. The purpose of this study was to comprehensively assess the perception of users of a query-based HIE platform regarding its effectiveness, especially with regard to the platform’s addition of COVID-19-related information and containment measures, as well as their potential to enhance the willingness of users for continued platform utilization.
Methods: During April to May of 2020, we surveyed 434 healthcare providers whom were users of a tertiary hospital’s HIE platform via validated self-report questionnaires. 121 questionnaires were deemed valid, with a response rate of 33.6%. No statistically significant difference was found between respondents and non-respondents in the various levels of healthcare providers after a goodness-of-fit test.
Results: Using the orthogonal rotation method of factor analysis for dimension reduction, we distinguished five latent factors, with a cumulative variance contribution of 82.95%, from thirtyone items of the HIE platform effectiveness assessment questionnaire. A statistically significant difference was only present in the scores of the five factors when the respondent was a physician. The five factors, including two COVID-19 containment factors, were effective in predicting whether users would continue to use the HIE platform, with a predictive power of 68.64%.
Conclusions: The timing and accuracy of information is crucial to the establishment of any platform in today’s age of fast-paced technologies. When addressing user-generated queries, an empathetic attitude from the platform’s administrator is the most decisive factor with regard to the level of satisfaction in using the platform. In addition, the quality of information and services of the HIE platform, the usefulness of COVID-19 epidemic prevention-related information, the interface functionality and systematic operation of the platform, and the effectiveness of epidemic containment measures and resource utilization were strong predictive factors of the continued use of the platform. These factors will be used as benchmarks by the heads of various medical institutions to evaluate platforms’ effectiveness in curbing the spread of pandemics such as COVID-19.
